Description
Dispositivo de frenado electromagnético para la coquilla de una instalación de colada en cuerda.Electromagnetic braking device for coquilla of a installation of laundry in rope.
La invención se refiere a un dispositivo de frenado electromagnético para el caldo de acero que afluye a la coquilla de colada en cuerda de una instalación de colada en cuerda, que se compone al menos de una bobina asociada a los lados anchos de la coquilla con un núcleo ferromagnético y al menos de un yugo asociado al mismo.The invention relates to a device of electromagnetic braking for the steel broth that flows to the rope casting shell of a rope casting facility, which is composed of at least one coil associated with the wide sides of the shell with a ferromagnetic core and at least one yoke associated to it.
Se conocen instalaciones de colada en cuerda de la clase constructiva citada al inicio. El chorro de colada que afluye a la coquilla se frena y orienta para reducir turbulencias, mediante un campo magnético que actúa entre los lados anchos de la coquilla de colada en cuerda. Para generar el campo magnético se han aplicado a placas de cobre del lado ancho de la coquilla de colada en cuerda núcleos ferromagnéticos, que se excitan mediante bobinas que los circundan. El frenado y la orientación del chorro de colada provocados por el campo magnético produce una estabilización del baño de acero y una reducción de turbulencias en el interior del baño de acero, con el objetivo de la colada uniforme de cuerdas de acero.Rope casting facilities are known for the construction class cited at the beginning. The pouring jet that flows to the shell is braked and oriented to reduce turbulence, by a magnetic field that acts between the wide sides of the rope laundry. To generate the magnetic field they have applied to copper plates on the wide side of the casting shell in rope ferromagnetic cores, which are excited by coils that surround them. Braking and orientation of the pouring jet caused by the magnetic field produces a stabilization of the Steel bath and a reduction in turbulence inside the Steel bath, with the aim of uniform laundry of ropes steel.
En el estado de la técnica se conoce una disposición integrada del dispositivo de frenado magnético, estando aplicados los núcleos ferromagnéticos y las bobinas por las que circula corriente fijamente a la coquilla. Según la ejecución, estos componentes del dispositivo de frenado poseen un peso considerable, que debe ser soportado por la mesa elevadora y por ello ser arrastrado. En el caso de la disposición integrada del dispositivo de frenado existe el inconveniente de las elevadas masas oscilantes y mayores tiempos de cambio para el acoplamiento y desacoplamiento de las conexiones de agua y eléctricas. Aparte de esto, el dispositivo de frenado electromagnético dificulta la evacuación de calor necesaria desde las placas de cobre de la coquilla. Por último debe preverse una cantidad relativamente elevada de frenos electromagnéticos por coquilla.In the state of the art a integrated arrangement of the magnetic braking device, being applied the ferromagnetic cores and the coils by which current flows fixedly to the shell. Depending on the execution, these components of the braking device have a considerable weight, which must be supported by the lifting table and therefore be dragged. In the case of the integrated arrangement of the device of braking there is the inconvenience of the high oscillating masses and longer change times for coupling and decoupling of water and electrical connections. Apart from this, the electromagnetic braking device hinders the evacuation of heat needed from the copper plates of the shell. By last a relatively high amount of brakes should be provided electromagnetic coquilla.
En el estado de la técnica se conoce también una disposición externa de un freno electromagnético, estando dispuestos el núcleo electromagnético y la bobina por la que circula corriente con movimiento en la instalación. Con la disposición externa de la bobina y del núcleo pueden obtenerse menores masas oscilantes. Los tiempos de cambio pueden reducirse considerablemente, ya que puede prescindirse el acoplamiento y el desacoplamiento de conexiones de agua y eléctricas. Por último sólo es necesario prever una cantidad relativamente baja de frenos electromagnéticos, precisamente sólo un freno electromagnético por cuerda de colada.In the state of the art, a external arrangement of an electromagnetic brake, being arranged the electromagnetic core and the coil through which current flows with movement in the installation. With the external arrangement of the coil and core can be obtained smaller oscillating masses. The change times can be reduced considerably, since it can dispense the coupling and decoupling of connections from Water and electrical. Finally, it is only necessary to provide a quantity relatively low electromagnetic brakes, just just a electromagnetic brake by casting rope.
Del documento DE 198 07 842 A1 se conoce una instalación de colada en cuerda con un dispositivo de frenado electromagnético, que se compone al menos de una bobina asociada a los lados anchos de coquilla con un núcleo ferromagnético y al menos un yugo asociado al mismo. Al menos partes aisladas del dispositivo de frenado electromagnético son componentes portantes de la coquilla de colada en cuerda. El campo magnético generado por el dispositivo de frenado electromagnético está dividido, con relación a la coquilla de colada en cuerda, en al menos un campo magnético superior y otro inferior. Al menos el interior de los núcleos electromagnéticos forma al mismo tiempo cámaras de refrigeración, a través de las cuales se produce la alimentación de agua de refrigeración y la línea de evacuación de agua. Mediante la integración del dispositivo de frenado electromagnético como componente portante en la coquilla de colada en cuerda, aunque se ahorra considerablemente en peso las masas oscilantes son relativamente elevadas.From document DE 198 07 842 A1 a known rope casting installation with a braking device electromagnetic, which is composed of at least one coil associated with the wide sides of the shell with a ferromagnetic core and at least a yoke associated with it. At least isolated parts of the device Electromagnetic braking are bearing components of the shell of rope laundry. The magnetic field generated by the device electromagnetic braking is divided, relative to the colada strand, in at least one magnetic field upper and lower. At least the inside of the cores electromagnetic forms at the same time cooling chambers, to through which the water feed of cooling and water evacuation line. By means of the integration of the electromagnetic braking device as bearing component in the rope casting shell, although saves considerably in weight the oscillating masses are relatively high.
La tarea de la presente invención es mejorar las disposiciones antes descritas de frenos electromagnéticos en coquillas de colada en cuerda, en especial la tendencia a ladearse como consecuencia de la alimentación axial mediante un guiado de trineo o carro con gran necesidad de espacio y peso y hacer posible o facilitar la posibilidad de ampliación, por ejemplo en las instalaciones de colada en cuerda existentes.The task of the present invention is to improve the provisions described above of electromagnetic brakes in rope coke shells, especially the tendency to tilt as a result of axial feeding by guiding sled or car with great need for space and weight and make possible or facilitate the possibility of extension, for example in existing rope casting facilities.
La solución de la tarea se produce, en el caso de la clase constructiva de un freno electromagnético según el preámbulo de la reivindicación 1, por medio de que el dispositivo de frenado electromagnético compuesto de yugo, bobina por la que circula corriente y núcleo ferromagnético en o sobre la coquilla de colada en cuerda está configurado de forma basculante hacia dentro o hacia fuera al menos mediante un medio de ajuste. El basculamiento mecánico hacia dentro o hacia fuera del freno se produce con preferencia por medio de, en cada caso, dos palancas no paralelas de diferente longitud. Por medio de esto se crea, a pesar del soporte de bancada de rodadura existente para el carro de acanaladura de distribución, la premisa para una óptima posibilidad de ampliación de instalaciones existentes con el dispositivo de frenado conforme a la invención.The solution of the task occurs, in the case of the construction class of an electromagnetic brake according to the preamble of claim 1, by means of which the device of yoke electromagnetic braking, coil by which current and ferromagnetic core circulates in or over the shell of rope casting is set in a tilting inward or out at least by means of adjustment. Tipping mechanical in or out of the brake occurs with preference by means of, in each case, two non-parallel levers of different length Through this it is created, despite the support of existing tread for the groove carriage of distribution, the premise for an optimal possibility of expansion of existing installations with the braking device according to the invention.
En la configuración del freno electromagnético está previsto que el freno compuesto de yugo, bobina por la que circula corriente y núcleo ferromagnético no puede oscilar junto con la coquilla de colada en cuerda.In the electromagnetic brake configuration it is planned that the brake composed of yoke, coil by which current flows and ferromagnetic core cannot oscillate along with the rope casting shell.
Mediante las medidas conforme a la invención se consigue ventajosamente que el freno electromagnético sea independiente de la coquilla de colada en cuerda, por lo que puede intercambiarse más fácilmente y que las masas oscilantes permanezcan limitadas a las piezas constructivas de la coquilla de colada en cuerda y no sea necesario que oscilen además masas adicionales de las piezas constructivas del freno electromagnético.By means of the measures according to the invention, advantageously get the electromagnetic brake to be independent of the rope casting shell, so it can exchange more easily and that the oscillating masses remain limited to the construction parts of the casting shell in rope and it is not necessary to oscillate additional masses of the construction parts of the electromagnetic brake.
En una configuración ulterior de la invención está previsto que la posición de trabajo del freno electromagnético esté configurada de forma adaptable a la coquilla mediante una limitación mecánica de recorrido o que su posición de trabajo esté determinada por limitaciones de recorrido ajustables. Aparte de esto se propone que su posición de reposo esté determinada al menos por medio de un tope.In a further configuration of the invention The working position of the electromagnetic brake is provided is configured in an adaptable way to the shell by means of a mechanical travel limitation or that your working position is determined by adjustable travel limitations. Apart of this it is proposed that your resting position be determined at least by half a stop.
Para una configuración ulterior del freno electromagnético conforme a la invención se propone que, para reducir la distancia entre polos y para aumentar la efectividad en el depósito de agua no magnético, esté dispuesto un núcleo parcial magnético.For further brake configuration electromagnetic according to the invention it is proposed that, for reduce the distance between poles and to increase effectiveness in the non-magnetic water tank, a partial core is arranged magnetic.
La invención se describe con más detalle con base en un ejemplo de ejecución, del que pueden deducirse otros detalles y ventajas de la invención. Aquí muestran:The invention is described in more detail based in an example of execution, from which other details can be deduced and advantages of the invention. Here they show:
la figura 1 la posición de trabajo del freno electromagnético,Figure 1 brake working position electromagnetic,
la figura 2 la posición de reposo del freno electromagnético.Figure 2 brake rest position electromagnetic.
Las figuras 1 y 2 muestran el freno electromagnético conforme a la invención, compuesto de yugo 7, bobina 3 por la que circula corriente y núcleo ferromagnético 5. El freno electromagnético debe fijarse al soporte de bancada de rodadura 11 por medio de, en cada caso, dos palancas 9, 10 no paralelas de diferente longitud y articularse centralmente a través de un medio de ajuste 8, por ejemplo un cilindro hidráulico. Por un lado el movimiento en curva del freno electromagnético conseguido por medio de esto hace posible un movimiento casi horizontal del mismo, desde el depósito de agua 2 y hacia fuera del bastidor 1 de la coquilla. Por otro lado la posición de reposo con ahorro de espacio entre el soporte de bancada de rodadura 11 y la coquilla garantiza un cambio sin problemas de la coquilla y de los segmentos de guiado de cuerda. Por lo demás esta disposición permite tanto un recorrido más corto como una menor fuerza de ajuste como un reparto lineal, ya que el sistema se encuentra cerca de su punto muerto superior. La coquilla de colada en cuerda y el freno electromagnético son piezas constructivas independientes, de tal manera que para el cálculo de las fuerzas oscilatorias sólo deben tenerse en cuenta las masas a mover de las piezas constructivas de coquilla. La figura 1 muestra el freno electromagnético en la posición de trabajo. En la posición de trabajo una limitación de recorrido 8 ajustable determina la posición. La figura 2 muestra la posición de reposo del freno electromagnético. En la posición de reposo el freno descansa sobre los topes 4.Figures 1 and 2 show the brake electromagnetic according to the invention, composed of yoke 7, coil 3 through which current and ferromagnetic core circulates 5. The electromagnetic brake must be fixed to the bed support of rolling 11 by means of, in each case, two levers 9, 10 not parallels of different length and articulate centrally through of an adjustment means 8, for example a hydraulic cylinder. For side the curved movement of the electromagnetic brake achieved by means of this it makes possible an almost horizontal movement of the same, from the water tank 2 and out of the frame 1 of the shell On the other hand the resting position with savings of space between raceway support 11 and the shell guarantees a smooth change of the shell and segments of rope guidance. Otherwise this provision allows both a shorter travel as a lower adjustment force as a cast linear, since the system is near its neutral higher. The colada of colada in rope and the brake electromagnetic are independent construction pieces, of such so that for the calculation of oscillatory forces they should only take into account the masses to move of the construction pieces of coquilla Figure 1 shows the electromagnetic brake in the work position. In the work position a limitation of Adjustable travel 8 determines the position. Figure 2 shows the rest position of the electromagnetic brake. In the position of rest the brake rests on the stops 4.
